Automatic Email List Cleaning

A quick overview of our complimentary email list cleaning service

Flodesk automatically checks and filters email addresses to help you maintain a healthy list and protect your sender reputation.
Our system detects invalid, role-based, or risky email addresses and updates their subscriber status accordingly, at no extra cost.

​

Email list cleaning identifies and flags invalid or risky email addresses that could harm your deliverability or cause bounces.

In Flodesk, “cleaning” means the subscriber’s status becomes "Cleaned".
Subscribers with this status can’t receive emails.

Cleaning your email list

• improves your sender reputation and deliverability

• reduces your bounce rates and

• prevents spam signups.

Email scrubbing is typically a paid service and the cost depends on the size of the email list that you want to be checked and have cleaned.

But here at Flodesk, email list cleaning is free for all Flodesk members.

​

Flodesk will perform a check for all subscriber sources including:

• Subscriber import via CSV

• Sync via Flodesk API including partner integration + API-key

• Manual creation

• Form opt-in

• Opt-in via a checkout

Our real-time Email Validation API verifies your email addresses through a variety of methods, such as syntax validation, inbox availability, spam trap detection, role-based email detection and more.

Note: Role-based addresses are usually company emails assigned to a job position rather than an individual. These addresses are often overseen by multiple people and can eventually become inactive. Due to their association with high bounce rates and spam complaints, we exclude them from being imported via a CSV.

Such role-based email addresses that are removed during a CSV upload include:

• abuse@

• admin@

• billing@

• compliance@

• contact@

• customerservice@

• data@

• devnull@

• dns@

• ftp@

• hostmaster@

• hr@

• info@

• inoc@

• ispfeedback@

• ispsupport@

• list-request@

• list@

• maildaemon@

• noc@

• no-reply@

• noreply@

• null@

• phish@

• phishing@

• postmaster@

• privacy@

• recruit@

• registrar@

• root@

• security@

• spam@

• support@

• sysadmin@

• tech@

• undisclosed-recipients@

• unsubscribe@

• usenet@

• uucp@

• webmaster@

• www@

Important: Subscribers with role-based addresses can still join your emailing list via a double opt-in form to ensure permission passed.

To find cleaned addresses:

1. Go to Audience → All subscribers

2. Click Filters

3. Select Status → Cleaned

You can export this list as a CSV for your records, but these subscribers can’t receive emails unless they re-subscribe through a Flodesk form.

Note: If an email address repeatedly soft bounces, the address will eventually be considered a hard bounce and cleaned from your audience. Subscribers will be marked as “cleaned” in case of repeated soft bounces, when

• A subscriber has 6 soft bounces with no activity

• A subscriber has 15 soft bounces with previous activity

• A subscriber hasn’t opened an email in 12 months and has over 15 mailbox full bounces

When you upload a new CSV file to Flodesk, we automatically check your list and filter out bad email addresses. Unlike elsewhere, this email list cleaning service is free for all Flodesk members. You can find cleaned email addresses by using the Filter on the Audience > All subscribers page.
